Balanced equation

Balance the chemical equation algebraically: H_2O + Al(NO_3)_3 ⟶ O_2 + H_2 + HNO_3 + Al Add stoichiometric coefficients, c_i, to the reactants and products: c_1 H_2O + c_2 Al(NO_3)_3 ⟶ c_3 O_2 + c_4 H_2 + c_5 HNO_3 + c_6 Al Set the number of atoms in the reactants equal to the number of atoms in the products for H, O, Al and N: H: | 2 c_1 = 2 c_4 + c_5 O: | c_1 + 9 c_2 = 2 c_3 + 3 c_5 Al: | c_2 = c_6 N: | 3 c_2 = c_5 Since the coefficients are relative quantities and underdetermined, choose a coefficient to set arbitrarily. To keep the coefficients small, the arbitrary value is ordinarily one. For instance, set c_4 = 1 and solve the system of equations for the remaining coefficients: c_2 = (2 c_1)/3 - 2/3 c_3 = c_1/2 c_4 = 1 c_5 = 2 c_1 - 2 c_6 = (2 c_1)/3 - 2/3 The resulting system of equations is still underdetermined, so an additional coefficient must be set arbitrarily. Set c_1 = 4 and solve for the remaining coefficients: c_1 = 4 c_2 = 2 c_3 = 2 c_4 = 1 c_5 = 6 c_6 = 2 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: |   | 4 H_2O + 2 Al(NO_3)_3 ⟶ 2 O_2 + H_2 + 6 HNO_3 + 2 Al
